| 英文摘要 | In this paper, the electron screening effects on alpha-decay half-lives are investigated in different external environments, including a decays in neutral atoms, in metal, and in extremely strong magnetic-field environments. Systematic calculations of alpha-decay half-lives are performed for alpha emitters with proton number Z = 52-105. By taking into account the electron screening effects, the interaction potential between alpha particle and daughter nucleus, and the decay energy are both changed in external environments. From the numerical results, it is found that the alpha-decay half-lives in external environments are changed by a factor of from 5 x 10(-4)% to 11.46% due to the electron screening effects. Moreover, we find that the electron screening effect is closely related to the decay energy of the bare nucleus and its proton number. To measure the electron screening effects in experiments, it is suggested to select the alpha-decay candidates with relatively low decay energies and proper decay half-lives. |
